Minecraft Region Fixer

By Alejandro Aguilera (Fenixin)

Locates problems and tries to fix Minecraft worlds (or region files).

Minecraft Region Fixer tries to fix corrupted chunks in region files using old backup copies of the Minecraft world. If you don't have a copy, you can eliminate the corrupted chunks making Minecraft regenerate them.

It also scans the 'level.dat' file and the player '*.dat' and tries to read them. If there are any problems it prints warnings. At the moment it doesn't fix any problem in these files.

Supported platforms

This program only works with Python 3.x, and DOESN'T work with python 2.x. There was a Windows .exe for older versions, but right now you need to install the python interpreter to run this program.

Notes

Older versions of Minecraft had big problems when loading broken worlds. Newer versions of Minecraft are improving the way they deal with corruption and other things.

Region-Fixer still is useful for replacing chunks/regions with a backup, removing entities, or trying to see what's going wrong with your world.

Usage

You can read the program help running: "python regionfixer.py --help"
